MECHANICAL MOTOR.

SPECIFICATION forming part of Letters Patent No. 629,343, dated July 25,1899.

Application filed January s. 1298.

To all whom it may concern:

Be it known that we, HENRY S. DURAND, of Rochester, in the county ofMonroe, and ROB- ERT M. BECK and ROBERT K. MGLELLAN, of

New York city, in the county of New York, State of New York, citizens ofthe United States, have inventeda certain new and useful Improvement inMechanical Motors, of which the following is a full, clear, and exact todescription, reference being-made to the accompanying drawings, formingpart of thisspecification.

This invention relates to improvements in motors which are actuated byfoot-power and I 5 which are adapted to impart to the shaftof, ascrew-propeller of a small boat the proper motion to enable the boat tobe driven'by. means of such a motor, in connection withthje propellerand its shaft, by a person sitting in the boat; and the inventionconsists ofja mechanical motor constructed and adapted-to be operatedsubstantially as is shown by the accompanying drawings and as ishereinafter described and claimed.

On the accompanying sheets of drawings,- Figure l is a side elevation ofthe motor; Fig. 2, a rear elevation, being a View in the direc. tionindicated by the arrow near the right of- Fig. 1; Fig.3, a sideelevation of the motor 0 with supplementary means adapting it to be.operated by two persons sitting before it as well as by the personnaturally sitting behind it; Big. 4, a detail of particular parts whichappear in Fig. 3; and Fig- 5, a view of the 5 motor as it appears whenin use in a boat, a

portion of the boat being broken-away to expose the motor and the feetand legs of the persons operating it. o 4

Similar reference-numerals designate like 0 parts in diiferent Views.

Theobject of this invention is to produce a motor which maybe operatedby a person sitting on a seat like an ordinary chair, the motor beingstationed in front of him and being driven by the legs acting astoggles, their force being exerted against the back of the seat andagainst pedals "which move alternately forward and backward from andto-' ward the seat-back in courses which are fol- Serial No. 665,341.(No model.)

11, and on each upright is'a projection 12, in

which is a recess 12'. In the lower and forward part of the frame is ashaft2, which projects from the sides of the frame and on which arecrank-arms 20,, extending in opposite directions from the shaft. Eachcrankarm is connected to" a beam 3 by a link 4:.

The beams 3 are pivoted on the projections 12 of the frame, the lengthof each beam .being preferably a little more than two and onehalftimesthe length of one of the crankarms and the elevation of the axis ofthe beams above that of the shaft 2 being a little less than the lengthof one of the beams. The length of the links 4 is such that when thecrank-arms are parallel to the base that one of the beamsS which isconnected to the forward crank-arm is nearly vertical. The relations toeach other of the crank-arms,

beams 3," and links 4 being as described, the

lower endsof the beams and rear ends of the links travel forward andbackward during each revolution imparted to the shaft 2 along arcswhose'rear extremities are nearer'to a horizontal plane containing theirforward ex-' these pins and those of the other beam extending throughthe outer portions of the pro jections l2 and through the rear ends ofthe links 4. The upper ends of the bars 3' are contained in therecesseslil in' thefprojections 12. The function of these bars is toreinforce the beams 23, so as to help prevent ings, as well as those ofthe crank-arms and links 4; and ofthe shaft 2, are ball-bearings.

Each of the beams 3 is provided at its lower end with projections 80and31, and foot rests or pedals 30 and 31 are attached to theseprojections. Acord or strap 32, provided at its rear end with a handle,is sometimes attached, as shown, to each of the pins on which thefoot-rests 30 are mounted, and such cords or straps might be attached topins project,- ing from the pedals 31. The pedals 31 are intended to beused only when two persons operate the motor, although one person mightoperate it by means of these pedals instead of the others mentioned.

The shaft 2 carries a large gear-wheel 21, which is tight on the shaft.Below and behind this shaft is another shaft 5. The latter shaft isparallel to the shaft 2 and hasits bearings in blocks 13, which arebolted to the uprights 10. It carries a pinion 50 and a bevel-gear 51,havinga common hub,by which they are keyed to the shaft. The gear 21engages the pinion 50. A shaft 52for example, a propeller-shaft havingone of its hearings in the block or bracket 53, fixed on the base1--carries a small bevel-pinion 54, with which the bevel-gear 51engages. The bolt-holes in the bearing-blocks 13 are slots, and on theseblocks are arms 14, which extend to the block 53 and are attachedthereto by screws passing through slots in the arms. The slots mentionedfacilitate the adjustment of the gears 50 and 51 to bring them intoproper relations with the gears 21 and 54.

Balance-wheels 55'and 56' are secured on the shafts 52 and 5,respectively, and on a shaft journaled in the uprights above and behindthe shaft 2 another balance-Wheel 57 is keyed, together with a pinion58, which is engaged by the gear 21. The mechanism between the uprightsis inclosed in a case, portions of which are shown in Figs. 1 and 2.

The direction of the forward motion of the cranks is indicated by thearrow near the left of Fig. 1. \Vhen the motor is operated by one persononly, he naturally sits behind it, pushing against the pedals 30, hisposition there being more favorable than another which he might occupyin front of the motor, with his feet on the pedals 31. The effectiveresult-ants of the power applied by the legs to the pedals 30 aretransmitted by the links f to the crank-arms 20, causing the shaft 2 andgear 21 to rotate and toimpart motion to the shaft 52 through the gears50, 51, and 54.

If it is desirable to provide for the operation of the motor by severalpersons all facing in the same direction, so that, for example, a boatmay be propelled by a crew operating the motor, that is done by theaddition to the machine described of the means illustrated in connectionWith it in Fig. 3. In front of the motor and at suitable distances fromit and from each other are stationed standards of every standard, andeach of the beams 3 is reinforced by a bar 3, similar to the bars 3, thebeams and bars being connected together at their ends by thebearing-pins, as are the beams and bars 3 and 3. The beams 3 are alittle farther apart than are the beams 3 of the motor, each of thebeams 3 and its reinforcingbar 3" being so arranged that the outer faceof the bar and that of the projection 31 on the corresponding beam ofthe motor are in the same Vertical plane. Between the lower end of eachof the beams 3" and that of its reinforcingbar 3' is a block 40, mountedloosely on the bearing-pin, these blocks being provided with nipples 41.The beams on the forward standard are connected with those of thestandard behind it and with those of the motor by rods 4: These rods arecomposed of sections which are screwedinto the nipples 41 of the blocks40 and which are of proper lengths to keep the beams of each series, orthose which are connected together by each rod, substantially parallelto one another. The rear sections of the rods 4 are provided with eyesby which they are pivoted on studs'on the projections 31 ofthe beams 33,the studs being affixed to the projections 31 in place of the pedals 31;but the bars 4 might be pivoted to the lower ends of the beams 3 properinstead of to the projections 31. The bearings at the ends of the beams3" and those at the ends of the rods Lare ball-bearings. At the lowerend of each of the beams 3 is a pedal 30, which is secured to the beam,as represented in Fig. 4, and behind the motor and behind each of thestandards 10 a seat is fixed in the proper position to enable a personoccupying it to exert power most effectively upon the pair of pedalsnext in front of him.

To provide for the operation of the motor by four or more persons, thesupplementary means above described is extended by the addition of othersimilar means.

The rods 4 are made in sections to render it easy to lengthen or shortenthem, as may be desired; but a single continuous bar might besubstituted for each of these rods.

The motor is represented in Fig. 5 in its proper position in a boat. Itis fastened to the bottom of'the boat or a foundation close to thebottom or keel by screws or bolts passing through the ears 1' of thebase. The seat 6 behind the motor is preferably so arranged that theseat proper is a little above the axis of each of "the pedals 30 whenthe pedal is in its highest and most backward position and that the legof the person operating the motor, he sitting on the seat with his backagainst the seat-back, shall be straight, or nearly so, when the pedalis in its most forward position. He sits then well down in the boat,about as near to the bottom as a person commonly sits in a smallrow-boat, so that his weight tends to keep the boat steady, and,besides, his seat and its arrangement with respect to the motor are suchthat he can exertt-he full strength of his legs, acting as I was atoggles, against the back of the seat and the pedals of the motor. Themotion of each of the pedals-30' being forward and downward at thebeginning of each stroke, it is particularly favorable to the leg, sincethe force then exerted on the pedal acts on a line drawn from the kneeto the pedal, or in a direction which is nearly the same as that of thepedals arms during the backward movements of the pedals. v

Another person may act on the pedals 31" from a seat 6, placed-in frontof the motor,

as represented in Fig. 5. This seat is so arranged that the seat properis about level with the axis of either pedal, and the leg of the personis straight, or nearly so,when the pedal described. 1

is in its highest position.

"The relation of each of the seats 6" to the pair of pedals next infront of it is the same as that of the seat 6 to the pedals The forceexerted on the pedals30 is transmitted by the rods et to the beams 3,and thus acts upon the cranks in conjunction with that applied to themby the person sitting behind the Each ofthe seats should be adjustableforward and backward and vertically to render it easy to change itsposition, if necessary, to that which would best suitthe person who isto occupyithe seat.
